Garcia pleaded guilty to gross vehicular manslaughter while intoxicated, causing the death of James Steinmetz, and causing great bodily injury to his passenger Leisa Weddle.

She will be sentenced to serve 13 years in prison on May 29, prosecutors said.

Garcia was originally charged with murder and faced life in prison if convicted. Prosecutors were going to seek a murder conviction because Garcia had been convicted of DUI six months before the 2011 fatal collision.

At 8:30 a.m. on Jan. 19, 2011, CHP officers said Garcia was high on marijuana and an illegal stimulant when she drove a Jeep Cherokee the wrong-way on Highway 1 near Point Lobos and crashed head-on into another vehicle driven by James Steinmetz.

Steinmetz, 49, of Sacramento, died at the scene and Weddle suffered life-threatening injuries.

According to court records, even before the 2011 fatal crash, Garcia had a history of driving while under the influence of alcohol, marijuana and methamphetamine.
